Title:
EARTHQUAKE-SENSITIVE CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP2017212856
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an earthquake-sensitive circuit breaker capable of simply changing setting of earthquake intensity and quake duration and an earthquake intensity set value and quake duration set value already set once.SOLUTION: An earthquake-sensitive circuit breaker 10 includes: a current cutoff circuit 17 interposed in an energization wire 14 connected to a power supply and a load to cut off an energization current from the power supply to the load; an earthquake intensity detection unit 25 for detecting a quake and outputting an earthquake intensity signal expressing intensity of the quake; and a control device 31. The control device 31 includes a cutoff control section 32, a storage section 33, a signal input/output section 34, a serial transmission section 35, input connectors 36, 37, and a power supply circuit 38. A personal computer (PC) 40 can be connected to the input connector 37, and set values of earthquake intensity and quake duration are inputted from the PC 40 and stored in the storage section 33 as an earthquake intensity set value Is and a quake duration set value Js.SELECTED DRAWING: Figure 3
